The Frustration of Memory

Memory it can be a blessing and a curse at the same time. You can remember the wonderful time that you have spent with your friends having the time of your life but it can also switch into a curse that makes you recall the memories of pain, terror, and heartache. If memories bring the vastly two different parts out why would you want to remember anything? The when they are good memories are fantastic when they are bad its horrible. Sometimes I think if we could just get rid of the ones we don't want or bring pain we should be able to erase them. Obviously this isn't possible but I think the best thing to do in this situation would be to simply make more good memories than bad. What happens when it comes to memories of lost loves or people you really wish you would have a chance with? Would it be better to remember the parts when you would do anything under the sun for them or when you we killed when you were rejected?
